ROLE SUMMARY 

Babel Street is building mission-ready intelligence applications that help analysts move from signal to insight faster, with higher trust. As the Director of Design Engineering, you will own the end-to-end product experience key workflows—designing intuitive interfaces and shipping production-grade front-end code that integrates AI directly into the user journey. 

This is a “builder” role: you will pair human-centered design with strong front-end engineering to deliver experiences that feel simple, fast, and trustworthy—even when the underlying systems (data fusion, entity resolution, AI agents, multimodal analytics) are complex. You’ll collaborate tightly with Product, Platform, and AI teams to operationalize AI in the UI with guardrails, transparency, and human-machine teaming. 

This is a hybrid role working out of either our Reston, VA or our Somerville, MA office

WHAT YOU’LL DO (KEY RESPONSIBILITIES) 

Own the AI-first user experience for intelligence workflows 

  • Design and implement workflows where AI meaningfully reduces cognitive load (e.g., investigation setup, triage, summarization, entity linking, report generation, alert review). 
  • Build “AI-in-the-flow” patterns: inline suggestions, copilots, agent task panels, explainable recommendations, smart defaults, and guided wizards—without turning the product into a chat box. 
  • Define interaction patterns for agentic experiences (tasking, progress, tool calls, approvals, undo/redo, auditability, and fail-safe fallbacks). 

Human-Centered Design (HCD) with real users and real constraints 

  • Conduct lightweight user research (interviews, usability tests, workflow observation) and translate insights into journey maps, task flows, wireframes, prototypes, and shipped UI. 
  • Partner with Product to clarify user problems, success criteria, and tradeoffs—then execute quickly and iteratively. 
  • Ensure the UX supports novice-to-expert progression (discoverability for new users, speed and power features for experts). 

Build and ship high-quality front-end software 

  • Implement designs in a modern front-end stack (typically React + TypeScript), delivering clean, testable, accessible, performant UI. 
  • Build reusable components and patterns; contribute to (or lead) a design system using tools like Figma + Storybook. 
  • Instrument experiences with analytics/telemetry to measure adoption, workflow success, and time-to-insight improvements. 

Trust, safety, and transparency in AI experiences 

  • Design for “evidence-first” outputs: citations, sources, confidence indicators, what-changed diffs, and clear user controls. 
  • Implement guardrails in the UI: policy-aware interactions, redaction/PII-aware patterns (where applicable), and safe failure modes. 
  • Close the loop with feedback: capture user ratings, corrections, and outcomes to improve models and workflows over time. 

Cross-functional execution and leadership 

  • Work daily with Product, AI/ML, and Backend teams to define API contracts, data needs, latency targets, and UX acceptance criteria. 
  • Raise the bar on craft: advocate for coherent UX, consistent patterns, and high-quality delivery—while keeping momentum and pragmatism. 
  • Mentor others informally through design critiques, code reviews, and clear communication. 

 

WHAT YOU BRING (REQUIRED QUALIFICATIONS) 

  • 10+ years of experience delivering UX/UI design + front-end engineering for modern web applications (or equivalent depth). 
  • Strong portfolio demonstrating shipped product work (not just concepts)—including complex workflows and/or data-rich applications. 
  • Proficiency building production UIs with React and TypeScript (or comparable modern framework experience). 
  • Fluency in HCD methods: user interviews, task analysis, prototyping, usability testing, and iterative delivery. 
  • Strong product instincts: can translate ambiguity into clear workflows, make smart tradeoffs, and ship in increments. 
  • Experience integrating with APIs and data services; comfort collaborating on interface contracts and edge cases. 
  • Working knowledge of accessibility (WCAG fundamentals), performance basics, and secure UI patterns (auth, RBAC-aware UX).

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
